Attie Van Buuren


A highly experienced coach with more than 500 hours of coaching clients behind him. He is passionate about helping others identify and implement their own solutions by harnessing a greater power. His interactive skills and ability to channel individual crisis into pragmatic, but profoundly meaningful action makes him uniquely equipped to help clients integrate all facets of their lives into a coherent, purpose-driven direction. His background in the corporate world – which included stints in the sub-continent – also gives him specialized knowledge of cultural diversity within the coaching context and enables him to connect quickly with students and clients on a wide spectrum of levels.


He spent several years as an in- house coach at the Foundation Clinic and is still intensely involved in its activities, both as a group facilitator and trainer. Married with three children, he remains deeply committed to the foundation, its values and ideals due to his belief that the cure to addiction lies not in the external trappings of our lives, but within us. “Each individual is his or her own solution. Clean the cup inside and it will overflow with joy into everything outside it.”
